July 1, 1930. L, BORN GRPJDING MACHINE EZB f! Ill/TI Filed N 5 26II/l/l/I :55 a if [607 fs moa ATTORNEY UNITED STATES ATE LEON BORN, OFHAMPTON, VIRGINIA GRINDING MACHINE Application filed November 26, 1928.

The object of this invention is to provide,

in a device for grinding paint and other material, a removable andinterchangeable container or containers, so that a separate innercylinder may be employed for each color of paint, thereby avoiding theexpense and delay usuallyinvolved in the cleansing of cans when changingfrom one color to another.

A further object is to provide an outer rotatable casing, with drivingmeans therefor, and means for spacing and clamping the inner detachablecontainer in position, these retaining devices permitting of concentricand eccentric mounting.

With the foregoing and other objects in view, the invention consists inthe novel construction and arrangement of elements described,illustrated and claimed, it being understood that modificatmns may bemade within the scope of the claim without departing from the spirit ofthe invention.

In the drawings forming part of this application:

Figure 1 is a view of the device in vertical longitudinal section.

Figure 2 is a vertical transverse section on line 22 of Figure 1.

An outer casing or housing is designated 10 and includes end members inthe form of spiders or the like designated 11 and 12,

these elements carrying rigidly thereon disk members or the like 13 and14k formed with axle members 14' and 15, the latter being mounted inbearings such as 16 in vertical stationary elements 17 and 18.

Any suitable source of power will be employed for driving the devicethru pulley wheel 19 carried rigidly by axial member 14-.

Within the casing or housing 10, which is formed in two sectionshingedly connected at 10 and secured as shown conventionally at 10,Imount a cylinder or inner receptacle 20 adapted to receive the materialto be ground, this material being introduced thru an opening covered bya suitable closure 21. The material may also be withdrawn thru the sameopening, or liquid may be withdrawn thru a connection 24 which may becontrolled in any suitable manner as by means of a plug Serial No.322,061.

valve or the like 25. A vent opening may be provided, and closed in anysuitable manner.

In order to detachably mount the inner container 20 within the casing10, I employ threaded and adjustable clamping elements 30 having wingportions 31 on their outer ends, and controlling clamping plates or thelike 32 designed to positively engage the surface of the innerreceptacle 20.

In the grinding operation, balls or pebbles 33 are to be introduced withthe material to be operated upon, the apparatus acting as a pebble mill,and one important feature being that the inner container is not onlydetachable for the substitution of another container when a difierentcolor is to be introduced,but the inner element 20 may be mountedconcentrically or eccentrically, as desired, the eccentric movementbeing in tended under certain conditions to provide more pronouncedagitation. It will readily be understood that the devices 30 can be soadjusted that this concentric and eccentric position may be secured.

Having described the invention what is claimed is A device of thecharacter set forth comprising a cylindrical container having aremovable section, axles carried by the ends of the container and one ofsaid axles adapted for connection with a power source, vertical supportsreceiving the axles to support the container horizontally, a cylindricalfluid receptacle located in said container, adjustable wing elementscarried by the side walls of the container and having the wing portionsdisposed outwardly of said container, and plates carried by saidelements for engagement with the side walls of the receptacle to supportthe latter either concentrically or eccentrically with the container todecrease and increase the agitation of the fluid in the receptacleduring rotation of the device.

In testimony whereof I afiix my signature.

LEON BORN.
